* Converts A && A.B into A?.B (#54342) Implements the ?. operator, replacing code like A && A.B with A?.B BYOND Ref: When reading A?.B, it's equivalent to A && A.B except that A is only evaluated once, even if it's a complex expression like a proc call. * Converts all A && A.B into A?.B Co-authored-by: ZeWaka <zewakagamer@gmail.com>
